# MaPSS: Maths Postgraduate Seminar Series: Eric Hester -- How do you simulate a PDE? (with Dedalus)

Hello all,

MaPSS is back! The first seminar of the semester will be at 17:00 on Mon 30th Jul in
Carslaw 535. We’ve got a great speaker lined up, and as always it’ll be a great
opportunity to meet fellow postgrads and get free food!

Speaker: Eric Hester

Title: How do you simulate a PDE? (with Dedalus)

Abstract:  Partial Differential Equations are used to understand myriad phenomena:
the motion of birds in flight, wave generation by ships, bacterial growth and motility,
global weather systems, volcanic eruptions, animal pattern formation, and even traffic
jams. Despite this common mathematical framework, most codes only focus on how to
solve a very restricted subset of these problems.

This talk will be about Dedalus, an open-source, high-performance spectral code
for solving almost arbitrary PDEs in multiple dimensions. I’ll begin the talk with a
mini demo showing how Dedalus can use Chebyshev spectral methods to simulate
the KdV equation. Then I’ll go through and explain the key mathematics underlying
the code, and finish with a couple fun movies of how I’ve used Dedalus in my research.

See you there!
